Nothing truly otherworldly, but I've stumbled across a couple of nice bundles in the past:
1) 'Limited Edition' Gamegear/TV Tuner/Columns package, mint & boxed with powerpack, battery pack, screen magnifier and 16 boxed & complete games - £3
2) Woody six-switch VCS with 4 sticks, 2 paddles & 20 loose carts - £2
3) 7 3rd Party Dreamcast fishing rods for £1 each at Poundland. I put them all on eBay with a BIN of £10 and sold them all in 48 hours I also got 2 3rd Party N64 rumble packs, 4 3rd Party Saturn pads and a 6-button Megadrive pad at the same time, all for £1 each.
